Taxonomy of the Late Devonian placoderm remains from the Holy Cross Mountains, Poland, described by Gorizdro-Kulczycka (1934, 1950) and Kulczycki (1956, 1957), is revised. Several recently found specimens are also mentioned. The old collections are composed of representatives of Ptyctodontidae, Holonematidae, Plourdosteidae, Pholidosteidae, Selenosteidae, Titanichthyidae and Dinichthyidae, the latter with an undescribed species of Eastmanosteus. Newly found specimens belong to Ptyctodontidae, Plourdosteidae and Dinichthyidae. The occurrence of the Antiarcha in the Late Devonian of the Holy Cross Mountains, suggested by former authors, has not been confirmed.
